Need more space without leaving the home you love? Absolute Builders NY designs and builds dormer additions, full home additions, and rear or side extensions across Nassau and Suffolk — on time, on budget, and built to last.
Tell us about your project — we'll respond within 24 hours.
Whether you need a second story, a new family room, or a full rear extension — we plan, permit, and build the whole thing in-house.
Turn cramped attic space into a full second floor with bedrooms, bathrooms, and natural light. Our shed and full dormers are engineered for Long Island weather and matched to your home's character.
From a sun-drenched family room to a primary suite or in-law wing, additions are the smartest way to gain square footage without uprooting your life. We integrate seamlessly with your existing footprint.
Push out the back, the side, or wrap around to create the open-plan kitchen and living space your family actually uses. Modern glazing, vaulted ceilings, and indoor-outdoor flow — all done right.
No surprises, no hidden costs, no contractor disappearing acts. Here's exactly how your project goes.
We come to your home, listen to what you want, and walk through what's possible — no pressure.
You get drawings, materials, timeline, and a fixed price before a single permit is pulled.
We handle every permit and inspection. Our crew works clean, on schedule, and respectfully.
Final inspection together, full warranty paperwork, and the keys to your bigger, better home.
"We added a full shed dormer plus a rear extension to our cape — the house is unrecognizable in the best way. The project was completed on time, and the result was exceptional."John Carter Huntington, NY · Dormer & Extension Project
